1.3 Handheld Converter Ultrasonic Test
The Test key on the front panel of the SFX150 power supply is used to verify that the unit
is functioning (providing ultrasonic energy to the converter and microtip). The test key on
the power supply must be held, and then the pushbutton on the handheld converter must
be pressed for the system to perform an ultrasonic test.
Before testing the SFX150 system, always make sure that the microtip is not touching
anything. The system also performs several self-tests when it is first turned on.
Table 1.3 Ultrasonic Test
Step Do this... To obtain this result
1
Set up the SFX150 system following the
instructions in this manual.
If no microtip is currently installed,
mount the microtip to the handheld
converter. See 1.2 Handheld Converter
Setup and Operation for more
information.
Prepare the SFX150 system to
operate, if it was not previously
assembled.
2
After you have connected the microtip to
the handheld converter and verified all
other connections are as indicated in
Chapter 5: Installation and Setup in your
Sonifier power supply instruction
manual, turn on the unit and observe the
self-test displays.
Verify that the system passes all its
self-tests, observing that there are
no error messages on the front
panel display.
The SFX150 system advances to the
ready (rdy) mode and shows 'rdy'on
the display (see section 2.2.1
Sonifier Power Supply Front Panel
on your Sonifier power supply
instruction manual).
3
Adjust the Amplitude control to
approximately 50% (observe the value
on the front panel display). See Chapter
6: Operation in your Sonifier power
supply instruction manual to adjust the
amplitude.
Ensures that ultrasonic amplitude
will be at a mid-range value, and will
not cause damage if you were using
a microtip (which must be used at
less than 70%).
4
Verify that the microtip is not touching
anything.
Press and hold the test key on the front
panel of the power supply, then press the
handheld converter pushbutton. Observe
the front panel display.
Verifies the ultrasonic output of the
system. You may hear a soft, high-
pitched sound.
The display will show the output
power value. The test will run for 2
seconds, then stop.
5
If no alarms occurred during the Test,
you may either proceed with using the
system or turn the unit off. If an error
occurs, see section 7.4 Alarms/Errors in
your Sonifier power supply instruction
manual for more information.
Verification that the SFX150 system
is operating and is ready to be set
up for your experiment or
processing needs.
NOTICE
See section 7.3 Troubleshooting Chart in your Sonifier power supply instruction manual
if you have difficulties performing the above steps.
